August 12, 2025 — Ahu near Mokuʻāweoweo
Detailed Description
An ahu (cairn) marks the south end of Mokuʻāweoweo, the caldera at the summit of Mauna Loa. This photo shows the cone that formed during the Mauna Loa summit eruption in 1949, in the upper right. Most eruptions of Mauna Loa over the past several hundred years have started within the summit region, and about half have migrated into one of Mauna Loa's two rift zones from there.
